description, reference beinghad to the acfeed pipe sections that are coupled therecompanying drawings, forming a part of this specification. l p

My inventionrelates to filters and has for its obiect the provision of a filter of simplified construction and whose interior is readily accessible for the purpose of cleaning.

and replacement of parts.

In practising my invention I employ a chamber, which is preferably tubular, and which is provided at its ends with means for attaching sections of a feed pipe thereto whereby the chamber itself constitutes a feed pipe section that is alined with the with. The cylindrical or longitudinal wall of the chamber is providedwith cylindrical bosses for receiving closure caps, one of these bossesaifording access to a charcoal or carbon holding compartment and theother affording access to a trap space surrounding a pipethat projects intolthe chamber toward but short of the carbon; containing P boss15 I thread the exterior of this boss and portion of the chamber. By this construction I have provided a very simple form of filter which may be readilyinserted in feed or other liquid conducting pipes without disturbing the alinenient of the pipe sections. between which the filter is disposed and permitting the formation of a filter towhich access may readily be had.

I will explain my inventionmore fully by reference to the accompanying drawing showing the preferred embodiment thereof and in whichi Figure 1 illustrates a device of my invention as it may be installed; Fig. 2 is a sectional elevation on line 2 2 of Fig. ;1; and

Fig. 3 is a sectional. plan view on line 3 3 of Fig. 2. y y W Like parts are indicatedby similar characters of reference throughout the difi'erent figures. l The chamber 1 is desirably cylindrical.

The upperend wall 2 has an outsetting hol low cylindrical boss 3 which is threaded upon its interior to receive the lower threaded end of a sectiont of a feed pipe.

The lower endwall 5 has an outsetting hollow cylindricahboss 6 which is threaded, upon ts lnterior to receive the upper,

threaded end ofa section 7 of the feed pipe.

The tubular chamber 1 isthus adapted also to constitute a sectionof thefeed pipe and serves to couple the feed pipe sections 1 and 7 in alinement as the bosses 3 and 6 arecoaxial with the tubular cylinder 1. .Insetting annular flanges 8 and 9 areprovided for pcsirably a number of layers of wiresc-reen at granulated or subdivided carbon or a charcoal illustrated at 1 1. The carbon or other filtering medium holding space within: the chamber is adjacent the outlet end of the chamber... The cylindrical or longitudinal wall of the chamber 1 isprovided with an outsetting hollow cylindrical boss 15 through which access may be had to the spacing between the flanges for the purpose of is provided forholding the carbon in osirevent the passage of "water throughthe or replacing the carbon between the 1 screens.

carbon may-be The lower flange 9is located farenough above the bottom wall 5 to constitute a trap space in which the incoming water is initially received while on its way through the filtering carbon and the feed pipe section 4 leading tothe house servicepipes above. To

complete the trap partially formed by; the

. portion of the chamber 1 located below the flange 9 1' provide a short piece of pipeKZO gagement with an interiorly threaded insetting cylindrical boss 21. Tl he bosses 6 and 21 are co-axial whereby the pipe consti pipe portion 20 is thus co-aXial with the various feed pipe sections 1,.4L and 7, and as spacmg exists between the upper end of the pipe 20 and the lower screen 11, a trap isformed about the pipe 20 for receiving bodies of foreigi'i matter that are discharged over the upper end'of the pipe 20 into the trap space between the pipe. and the cylindrical wall of the chamber 1. ,The .spacing between the upper end of the pipe 20 and the j stitutes a pipe section and having end walls screen 11 is sufficiently largeto permit of the discharge of foreign matter to one side of the pipe 20 and is sufliciently small to prevent ready return of the larger bodies .of foreign matter, Thus any fish which may float into the trap may not readilyfind eXit therefrom. The screens 10 and ll'prevent upward passage of some of the foreign matter that will not settle around the pipe 20, while the carbon 14 serves to remove the smaller particles of foreign mat ter and to purify the upwardly flowing water.

It will be observed that the filtering medium, by filling the chamber adjacent its discharge end, serves definitely to divide the chamber into one portion that is exclusively for the accommodation of the filtering medium and another portion which is exclusively reserved for the trap space whereby all impurities that are collected in the trap space are forced to lodge under the filtering medium so as to be accessible through the opening affording admittance to the trap space.

From time to'timethe trap should be inspected and cleaned. To this end the lower portion of the cylindrical or longitudinal wall of the chamber 1 is provided with an outsetting hollowcylindric al boss 22 through which access may be had to the trap space about the pipe 20. I thread the exterior of this boss and screw upon it an interiorly threaded cap 23 and interpose between the cap and the end of the boss a packing disk 24: for preventing the leakage of water through the boss. The cap 23 is provided with a nutlike outsetting enlargement 25 to we enable the application of a wrench for applying and removing the cap.

constituting the chamber 1 a section of a feed pipe and providing it with means .8 and 6 for placing it in alinement with other feed pipe sections, I am'enabledto form a ter but there is no device with which I am familiar that is of the simple construction and which so readily ai'l'ords accessibility" to the parts thereof asthat which embodies my invention.

Having thus described my mventlon I claimas'new and deslre to secure by Letters v Patent the following l. A. filter includinga chamberthat conconstructed for the attachment of other pipe sections thereto; a filtering medium conchar 'e-end thereof' a iae within the cham- .berat the intake end thereof and through which liquid is passed into the chamber, spacing intervening between 13118131161 end of this pipe and the filtering medium and between the pipe and the longitudinal wall of the chamber whereby the pipe and the adjacent portion of the chamber cooperate to form a trap, longitudinal wall portions of the chamber having openings in position to afford access to the space of the trap and" to the space that contains thefiltermg medium; andcaps for covering said openings.

2. A filter including a chamber that constitutes a pipe section and having endv walls constructed for the attachment of other pipe sections thereto; a filtering medium confined within and filling the chamber ad- .jacent its discharge end; a plpe within the chamber at the, intake end thereof and through which liquid is passed into .the chamber, spacing intervening between the inner end of this pipe and the filtering medium and between the pipe and the longitudinal. Wall of the chamber whereby the pipe and the adjacent portion of the chamber cooperate to form a trap whose space does not "extend above the filtering medium, a longitudinal-wall portion of the chamber having an opening below the filtering medium in position to afford passage-from the space of the trap; and a closure for covering said opening.

In witness whereof, I hereunto subscribe my name this 13th day of May, A. D. 1912. HENRY N. LOOKER.
